What are hard metals and how are they different from other materials in terms of their physical properties?
Hard metals are materials that have high strength and resistance to wear and deformation. They are different from other materials in terms of their physical properties because they have a higher melting point, greater density, and are more difficult to shape or deform. Additionally, hard metals tend to be more brittle and have a higher level of conductivity compared to other materials.

Do different materials have the same resistance?
No, different materials have different resistance values. Resistance depends on the material's electrical properties, such as its conductivity and resistivity. For example, metals generally have low resistance due to their high conductivity, while insulators have high resistance due to their low conductivity.
What are the effects of force exerted on different materials?
The effects of force exerted on different materials can vary based on their properties. For example, ductile materials like metals can deform under force, while brittle materials may fracture. Elastic materials deform temporarily and return to their original shape once the force is removed, while plastic materials undergo permanent deformation.
Can a magnet pick up platinum gold?
No, platinum and gold are not magnetic, so they cannot be picked up by a magnet. They are both precious metals that have different properties than magnetic materials.
What is metalogy?
It seems like there might be a misspelling in your question. If you meant "metallography," it is the study of the physical structure and components of metals and alloys using microscopy and other techniques. It helps in understanding the properties and behavior of metal materials.
How does heat flow in different materials and substances?
Heat flows differently in different materials and substances based on their properties. In conductors like metals, heat flows quickly through the material due to the movement of free electrons. Insulators, on the other hand, do not allow heat to flow easily due to their tightly bound electrons. Some materials, like liquids and gases, transfer heat through convection, where hot particles rise and cold particles sink. Overall, the flow of heat in materials depends on their conductivity and physical structure.
What is physical metallurgy?
Physical metallurgy is the branch of materials science that focuses on the relationship between the structure and properties of metals and alloys. It involves studying the physical and mechanical properties of metallic materials, as well as the processes involved in their production, processing, and applications. Physical metallurgists work to understand how the microstructure of a material affects its properties and performance in various environments.
Can you use physical properties to tell different metals apart from each other?
yes
What are the three groups that materials fall into?
Materials can generally be categorized into three groups: metals, non-metals, and metalloids. Metals typically have properties like high electrical conductivity and luster, non-metals are generally poor conductors of electricity and have varied physical appearances, while metalloids exhibit properties of both metals and non-metals.
Can you use physical properties to tell the different metals apart from each other?
Yes, physical properties such as density, melting point, color, and conductivity can be used to distinguish between different metals. Each metal will have a unique combination of these properties that can help in identifying them.
What is an element whose physical properties are generally opposite to metals?
These chemical elements are nonmetals.
What is the malleability of hydrogen?
Hydrogen is not malleable in the same way that metals are. It is a gas at room temperature and does not exhibit the same physical properties as solid materials like metals.
What are some properties of mixed metals?
There are a number of physical properties that can be present in meted metals. These metals are often very dull in appearance for example.
Material are there in the world?
There are many materials in the world, including metals, plastics, wood, glass, and ceramics. These materials can be natural or synthetic, and they all have different properties and uses.
DO all non metals have the same physical properties?
no
What physical properties can be used to describe metals?
shiny
What characteristic of a metal allows it to conduct electricity?
The physical properties of different metals make them useful for different purposes in metals can move through the metal, allowing metals to conduct electricity.
When metal react with metal the result is?
When metals react with other metals, they can form metal alloys. These alloys have different properties compared to the pure metals and are often stronger and more resistant to corrosion. Mixing metals together can also alter their physical and chemical properties.
